HOIST.

Specification of Letters Patent.

Patented July 5, 1910.

To all whom it may concern:

Be it known that I, WILFRED ALMoN HARE, a subject of the King of GreatBritain, and resident of the city of Toronto, county of York, Provinceof Ontario, in the Dominion of Canada, have invented certain new anduseful Improvements in Hoists, of which the following is aspecification.

The invention relates to improvements in hoists, as described in thefollowing specification and illustrated in the accompanying drawingsthat form part of the same.

The invention consists essentially in the novel construction andarrangement of parts, whereby members for supporting the front end ofthe car and pivotally supported from the frame are operated to swingoutwardly by the operation of the hoist mechanism.

The objects of the invention are, to facilitate the removal of ashesfrom railway locomotives and the loading of same into ash cars, toprovide an elevated structure for raising the ash car which will notinterfere with the passage of another car or locomotive past the hoist,and to devise a neat, strong and simple form of hoist which may be usedfor loading ashes, coal or other loose materials.

In the drawings, Figure 1 is a side elevation of the hoist showing thecar in its unloading position in full lines and in its lowermostposition in dotted lines. Fig. 2 is a front elevation of the device, theflange of the car being partly broken away. Fig. 3 is an enlargedperspective detail showing the means for operating the extensiontrackway. Fig. 4 is a sectional detail showing the stop for limiting themovement of the extension track-way.

Like numerals of reference indicate corresponding parts in each figure.

Referrin to the drawings, 1 is the main frame of the hoist formed of theside up rights 2 rigidly supported at the to and bottom and bracedtoward the bottom by the cross braces 3.

4 is a cross beam extending between the uprights 2 intermediate of theirheight.

5 are the rails forming a permanent trackway for the ash car secured attheir ends 6 to the upper side of the cross beam 4;, the extremities ofsaid rails projecting outwardly slightly beyond said cross beam. Theralls 5 are curved downwardly from the inner side of the cross beam 4and extend angularly downward to the pit 7 arranged beneath the rails 8on which the locomotive, discharging its ashes, runs. The said rails 5are curved outwardly toward the lower end to bring the car beneath theopening 9 between the rails 8. The rails 5 are braced from the uprights2 by the struts 10.

11 are short lengths of rail rigidly secured to the outside of the rails5 and extending angularly upward beyond the curved portions of the saidrails 5 and rigidly supported from the main frame, the upper ends 12 ofsaid-rails being bent at an angle upward from the main portion. 7

13 is the ash car formed of a long scoop shape having the double flangedrear wheels 14 and the single flanged front wheels 15 journaled onsuitable axles.

16 is a bail pivotally secured to the outer ends of the rear axle of thecar 13.

17 is a rigid boom structure extending outwardly from the front side ofthe frame 1 and carrying the grooved sheave 18 in suitable journals atthe outer end thereof.

19 is a sheave suitably supported from the frame 1 in angulararrangement therewith and below the sheave 18.

20 is a double sheave journaled in suitable bearings in the sideextension frame 21 secured to one side of the frame 1.

22 is an air cylinder secured between the extension frame 21 and themain frame 1 at the bottom thereof having the piston rod 23 extendingfrom its upper end and supporting a double sheave '24:, said piston rodhaving a suitable piston secured to its opposite end.

25 is a grooved roller journaled on the outwardly extending end of theshaft 26 supporting the double sheave 24:.

27 is a flexible cable, at one end secured to the bail 16 of the ash car13 and extend ing around the sheave 18 under the sheave 19 and aroundthe double sheaves 20 and 24 and secured at its other end to the frame.

The operation of the piston of the air cylinder 22, through the cable27, operates the car 13 to be raised or lowered on its tracks. In theupward travel of the car the front wheels and the inner flanges of therear wheels travel on the, rails 5, and the forward end of the carfollows the upper curve of the said rails 5 leading to the ends 6. Therear wheels of the car having the flanges extending outwardly beyond therails engage the rails 11 and rise upwardly past thecurvedupperportionof said rails 55, the bail 16 swing ngfreely on the axle as.the car changes its position in relation to the angle of inclination oftherails 5.

one end of the cross beam 4, .said bracket 7 having the lugs 29 and 30extending there-r i stops on the bearings 39.

sleeve portion 34 journaled on the sha from and the ournal'bearing 31,

. "32 is a shaft rigidly secured in the lugs 29 andi and extendingtherebetween.

"33 is a beveled gear segment haVlIl%' tl16 t 32. 351s an arm extendingfrom the sleeve 34 at the opposite end to the segment33 and having. asocket 36 formed on its outer y :1 37 is a bentarim rigidly secured inthe sgcket'36. of the arm andadapted toengage the'g rooved roller25 inits downward movement.

.38-is a shaft j 'ournaled in the journal bearing 31 atone end and inthe bearings 39 supportedfrom thecross beam 4. 4Q is beveled, gear se'ment fixedly secured to one end of the sha t 38 and meshing with thesegment 33.-

, "41 are the extension rails having the hub portions 42 fixedly securedto the shaft 38,

saidhub portions havingthe stops 43 projecting from one end thereof,saidstops being adapted to engage the corresponding stop'p'ortions 44extending from the ends of the journal bearings 39. g

45,.is a lever fixedly secured to the shaft 38, at the opposite end tothe segment .40 and having the counter balance weight 46 adjustablysecured thereto, The counter balance ,is arranged to normally hold theextension rails-in the upright position shown in dottedlinesQin Fig. 1and when said rails are in a this position the arm 37 is swung throughthe inter-meshing gear segments to its upper 7 position.

' In theoperation of this device the locomo tive is brought overthe. ashpit and the ashes and cinderslfro-m the fire box are discharged into thecar 13. The air cylinder is then operated todraw downwardly on thecable, ,pulling- ,the car upwardly over the rails As the car approachesthe curved upper end of the rails5'the grooved roller 25' engages thearm swinging saidarm downwardly and. consequently. swinging the gearsegment '33 on the shaft 32; The swinging. of the segment 33 turns theshaft 38 in its bearings through the segment. 40, ele

jva-ting :the .icounterTbalance weight and throwing the extension rails41 downwardly totheir horizontal-position, the stops on the hubs of saidextensionma'ils engaging'the The roller 25 con inu i'en m tw hh tr i tp. tion of the bent-arm 37 during the remainder 'of its downward travel,thus holding the ex- 7 wheels of the car 13 pass over the curved portionof the rails 5 and continue onto the extension rails 41. The extensionflanges of the rear wheels of the car engage the rails 11 and travelingupwardly along said rails elevate the back end of the car, thus holdingthe said car so that the back Iendis elevated to cause the contents toslide out into the ash car or other receptacle brought underneath thesaid extension rails. The return movement of the air piston allows therear end of the car to drop and as the. front wheels withdraw from theextension rails the grooved roller 25 passes the shoulder on the arm '37and allows the said extension I railsto swing upwardly on their pivots,the counterbalance weight returning the parts to normal.

W A device such as described maybe placed beside arailwa-ytrack andutilized for the unloadingof loose materials of any kind from onevehicle and loading it upon another and does not-in any wayinterferewith trafiic on other lines as no part of the device extends over thetrack except when the conveyer car is actually discharging its load. Theextensionrails, provided to carry the car a sufficient distanceoutwardly to discharge" its load, return immediately to their normalposition after discharging its load. f The preferred form ofconstruction is herein shown and described but it must be understoodthat many of the parts may be changed considerably without departingfrom the spirit of the invention.
